TAKE-UP MECHANISM FOR LOONIS.

SPECIFICATION forming part of Letters Patent No. 787,281, dated April 11, 1905.

Application filed August 8,1904. Serial No. 219,857.

To all lr/lo /I- it may o/warn:

Be it known that we, RANDOLPH Cnour'rox and .louv h. FIT'HJN, citizens of the United States, residing at \Yorcester, county of Worcester. and State of Massachusetts, have invented an lnnn'ovement in Take-Up echanism tor Looms, of which the following description. in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to that class of loom take-up employii'ig a worm and worm-wheel for turning automatically the sand-roll or other parts for winding the cloth as itis woven, the object of our invention being to suspend at will the operation of the automatic means that the sand-rolls may be turned lreely while the worm and worm-wheel remain at rest, such provision saving very much valuable time ol the weaver.

Figure l in end elevation showsa loom provided wit h take-up mechanism embodying the invention tobeherein claimed. Fig. 2 is apartial front end view of the loom, Fig. l, with the worm-shaft and thecllitch-controllingshaft in section. Fig. 3 is a partial section taken through gear 4 on the sand-roller and gears 2 and I). Fig. t is a section on the line .1, Fig. 3, and Fig. 3 is a section on the line Fig. 3.

liet'erring to the drawings, A represents the end frame of a loom. ll the usual breastbeam, (,7 the usual take-up or sandroller, l) a clothguiding roller. it the cloth-receh'ing roller,

and F the cam-shaft, which parts may be all as common in looms.

The shaft F has applied to its end a bevelgearmthat engages a pinionu',mounted loosely on the end of a worm-shaft held in suitable bearings 1/ u, sustained by the loom side. Une end of the bevel-pinion H has a series of teeth 1/, that may be engaged by a series of teeth of a collar 0, connected with the wormshat't a" by a spline, so that said collar may be moved when desired longitudii'ially ot' the shaft u to cause the teeth of the collar to be r l l disengaged from the teeth of the continuouslyrotating bevel-pinion u when it is desired to stop the rotation of the worm-shaft a it being understood that when said collar and said worm-shaft are uncoupled the shaft remains at rest.

To control the collar and cause it to be disengaged from the continuously-rotating bevel-pinion It or to be engaged therewith, the collar is shown as provided with an annular groove that is entered by the forked end of a lever e, pivoted at y/ on an ear of the bearing a, said lever having connected with it at between its ends a rod (3, that is extended through a hole in the bearing It and provided beyond said bearing with a collar b lixed thereto, said collar being acted upon when desired by the lower end of a hand-lever (Z, secured to the end 1/ of the usual shipperrod,extended through the loom side. The shipper-rod is surrounded at the right-hand side of the bearing 1/ by a spring A and an adjustable collar A, the spring abutting one side o l the collar and the bearing. so that said spring acts normally to etl'ect the engagement of the collar I) with the teeth ol the pinion It and rotate the shal't 1/, provided with a worm a, that engages the teeth of a worm toothed wheel 1 secured to a shaft H, extending through the loom side, as shown, and provided with a gear 1, that engages a pinion 2, having allixed to one side of it a smaller pinion 3, that in turn engages the teeth of a toothed wheel -t, last on the axis or the journal ol the saml-roller. The toothed wheel L engages a pinion 5, that engages a pinion 6, that in turn engages a pinion T, mounted on the shaft 8, the latter when rotated turning the cloth-receiving roller F.

The outer end of the worm-shaft is provided with a hand-wheel f, having a pivoted handle or crankf. \\"hen the loom is runring and weaving is going on, the hand-lever 1/ occupies its dotted-line position, Fig. l, and the collar 1/ engages the teeth of the continuously-rotating bevel-pinion a, and the wormshaft and worm rotate the worm-wheel e automatically. Whenever an imperfect spot or fault in the cloth is discovered, the sand-roller and cloth-receiving roller must be turned backwardly, and the weft inserted in the warp is pulled out until perfect cloth is reached. It has been customary prior to our invention to disconnect the worm e from the worm-shaft and through a hand-wheel turn the worm backwardly to thus turn the worm-wheel and gearin g actuated thereby backwardly and also turn backwardly the sand-roller and unwind the cloth-receiving roll. WVhen the Worm e is employed to turn the worm-wheel, sand-roller, and other parts backwardly, a very considerable amount of time is necessary, and to expedite the turning backwardly of the sandroller and cloth receiving roller we have mounted the pinion 2 loosely on a stud h of a bracket 7/, held on a stand it, fast to the loomframe, and have provided the side of said pinion with a space to receive the end of a toothed sleeve if, that is surrounded by the small pinion 3, the latter and the sleeve being connected by a spline. (Shown best in Fig. 3.)

The stud 7L has an annular groove that is entered by a pin 10, extended through a hole in the sleeve and connected with a spring 12, fast at one end of the sleeve. WVhen it is desired to disconnect the train of driving mechanism between the sand-roller and the cloth-receiving roller, so that the sand roller may be turned backwardly without turning the wormwheel or the worm, it is only necessary to withdraw the pin 10 from the annular groove in the stud and engage the sleeve by its end and pull the same outwardly or to the left, Fig. 3, until the inner end of the sleeve is Withdrawn from the opening referred to in the side of the pinion 2. This done, the handwheel at of the sand-roller may be engaged by the hand and the latter turned backwardly, causing its toothed wheel L in engagement with pinion 3, then loose on the stud, to be rotated freely while the worm-wheel and worm remain at rest, and at the same time the clothreceiving roller will be turned in the corresponding direction through the pinions 5, 6, and 7, actuated by the gear 4.

We are not aware that prior to our invention intermediate gearing between the toothed wheel on the sand-roller and the usual wormwheel actuated by the worm on the loom-shaft has ever been so constructed as to be disengaged to run freely while the sand-roller is turned by hand. By this improvement very much time of the operator may be saved.

To suspend the operation of the worm-shaft a preparatory to turning the sand-roller backward or the take-up roller or the cloth-receiving roller backward, it is only necessary to move the hand-lever (Z from its dotted-line position into its full-line position, causing its end to act on the collar h and compress the spring It, thus moving the lever c to effect the unclutching of the collar b from the teeth of the continuously-moving bevel-pinion a.

Prior to this invention it had been customary to mount a worm used to rotate the wormwheel of the take-up mechanism on the sleeve capable of being temporarily disconnected from the shaft used to turn the worm for actuating the sand-roller when the cloth was to be run over the same backwardly to correct a fault in weaving, and to do this the sleeve and worm had to be turned by the hand of the operator, as stated, and this process is so very slow that the operator is tempted to keep on weaving, notwithstanding the fault in the cloth, rather than lose the time necessary to correct the fault. In our invention by simply disconnecting and leaving loose an intermediate pinion in the train of gearing between the usual worm-wheel and the toothed wheel on the sand-roller the latter is left entirely free to be turned readily by hand to give up its imperfect cloth to be corrected by the weaver.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination with a worm-wheel forming a part of a train of take-up mechanism, and a continuously-rotating gear a, of a worm-shaft having a worm, a toothed collar splined on said worm-shaft, and a bevel-pinion having teeth at one end and mounted loosely on said shaft, said bevel-pinion being adapted to be rotated continuously by said gear, a rod extended in the same direction as said shaft, and means operative on the stopping of the loom to move said rod and effect the disen gagement of said collar and bevel-pinion when it is desired to stop the worm-shaft and suspend the operation of the take-up mechanism.

2. In a take-11p mechanism, the combination with a Worm and worm-wheel, a sandrollerhaving an attached toothed wheel, and a driving-train intermediate the shaft of said worm-wheel and the wheel of the sand-roller, of means for disconnecting and leaving loose one of the intermediate pinions of said driving-train that the sand-roller may be turned freely while the worm-wheel and worm remain at rest.

3. In take-up mechanism for looms, the combination with a worm -wheel, its shaft, and a gear connected therewith, and a sandroller having a connected toothed wheel, of a pinion meshing with the gear carried by the shaft of the worm-wheel, a pinion meshing with the toothed wheel carried by the sandroller and means for temporarily disconnecting said pinions that the sand-roller may be turned by hand and leave the worm-wheel and its shaft at rest.
